Abstract

The disclosure describes an implantable medical lead for delivering stimulation to a patient. Electrodes may be located on two or more surfaces of the lead to, for example, selectively deliver stimulation to one or more tissue layers within the patient. The lead may be implanted within or between intra-dermal, deep dermal, or subcutaneous tissue layers, and may be used to, for example, deliver peripheral nerve field stimulation to treat pain experienced by the patient at the site at which the lead is implanted. The lead may comprise a paddle lead or a multiple level lead, e.g., a lead having a plurality of flat or paddle shaped lead bodies arranged in substantially parallel planes. Further, the lead may include fixation structures on the distal end, proximal end, or both ends to prevent migration.
